Abstract
The utility model discloses one kind of manufacture of tooling wear shoes and comprises following steps: A, with carbon steel or tungsten carbide preparation junk mill body; B, making the build-up welding layer on the junk mill body be in the down hand position, at first preheat the work piece with flame, then load onto the tight junk mill body of Welder's clamping, welding frock and junk mill body and the contact of build-up welding layer the material be austenitic stainless steel or copper alloy; C, carrying out the build-up welding with YD type carbide alloy welding rod on the junk mill body, the inside callipers is unclamped after accomplishing to the welding, and it can take off the welding frock. The junk mill manufacturing approach welding convenience of this utility model, build-up welding take shape, need not the secondary operation for the finished product promptly after the junk mill has welded.
Description
Technical field
The utility model relates to the auxiliary equipment of making oil exploitation underground work workpiece, specifically a kind of manufacturing frock that is used for the junk mill of down-hole grinding.
Background technology
Junk mill belongs to a kind of workover tool, is made of body and carbide alloy section, and the carbide alloy section is welded on bodies top, has the high advantage of grinding efficiency.The method of making has following two kinds: a kind of is the body of just reserving one section tubbiness when the junk mill body is made, external mold as pile-up welding hard alloy, this section external mold has just connected together with the alloy of built-up welding after welding is finished, and the effect when junk mill uses has just descended greatly like this; Another kind method is to add a frock in order to built-up welding in the junk mill periphery after the junk mill body is finished, and removes frock with cutting working method again after welding is finished, and has so not only bothered but also uneconomical.
The utility model content
The purpose of this utility model provides a kind of junk mill manufacture method and frock thereof of handling ease.
The technical solution of the utility model is as follows:
A kind of junk mill is made frock, this welding tooling comprises can be enclosed within this external frock body of junk mill, has the interior card that is used to clamp the junk mill body in the frock body, it is characterized in that: interior cartoon crosses screw rod and nut is installed on the frock body, the holding screw of regulating the welding tooling position also is installed on the frock body, and welding tooling is austenitic stainless steel or copper alloy with the material of the face that the junk mill body contacts with overlay cladding.
Supplementary technology scheme of the present utility model is as follows:
Preferably, card is 3 in described, and along the circumferential direction is distributed on frock body inboard.
Preferably, also be provided with and the identical wild card of interior card quantity in the frock body outside, screw rod passes wild card and is connected on the interior card, and the nut on the screw rod contacts with the wild card outer surface.
The beneficial effects of the utility model are: because the welding of YD type hard alloy composite material surfacing welding belongs to gas brazing, the tyre body alloy of this welding rod has good wellability to carbon steel and tungsten carbide particle at a certain temperature, tyre body alloy is relatively poor to the wellability of austenitic stainless steel under same temperature, and is relatively poor to the wellability of copper alloy.Therefore, utilize this difference, the material that the material of choose reasonable junk mill body and frock contact with overlay cladding, make alloy welding deposit and junk mill body firm welding can not connect together with frock again, convenient welding, built-up welding are shaped, after built-up welding is finished, frock unclamped to take off get final product, be finished product after junk mill has welded and need not secondary operations, improved the junk mill working (machining) efficiency, reduced production cost.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 be the utility model embodiment in weld deposit process, the installation diagram of junk mill body and welding tooling.
Fig. 2 is the schematic diagram of the welding tooling of the utility model use.
The specific embodiment
Specific embodiment of the utility model 1, a kind of frock that is applied to make in the junk mill process, as depicted in figs. 1 and 2, frock body 2 usefulness carbon steels are made, built-up welding contact layer 7 is＞the austenitic stainless steel overlay cladding of 5mm, car evenly was cut into trisection along axis 12 with body with wire cutting method after built-up welding was finished after finishing after given size, boring, tapping are finished, and with interior card 3, wild card 4, screw rod 6 and nut 5 body of trisection was combined into round frock body 2.Card 3 position in can regulating by the cooperation of screw rod 6 and nut 5, interior card 3 usefulness austenitic stainless steels are made.On frock body 2, also have holding screw 1, be used to adjust the relative position of frock body 2 and junk mill body 9.When using present embodiment frock processing junk mill, comprise the steps:
One, material is prepared:
1, uses steel alloy 35C
RM
OOr tungsten carbide is made junk mill body 9;
2, prepare welding tooling, this frock comprises the frock body 2 that can be enclosed within outside the junk mill body 9, and frock body 2 is made of jointly three block parts, and forms a ring-type integral body.Have 3 (or a plurality of) the interior card 3 and the wild card 4 that are used to clamp junk mill body 9 in the frock body of trisection, interior card 3 is used to tighten the junk mill body, in this example wild card 4 be mainly used in three block parts connect do as a whole, and as the location benchmark of interior card 3; Interior card 3 and wild card 4 are installed on the frock body 2 by screw rod 6 and nut 5, and the holding screw 1 of regulating the welding tooling position also is installed on frock body 2, and the material of the built-up welding contact layer 7 of frock body inboard is an austenitic stainless steel;
Two, welding:
As shown in Figure 1, the first step is horizontal junk mill body 9 tops; Second step was preheated to about 600 ℃ junk mill body 9 tops with flame, was used to obtain better built-up welding effect, and produced excessive stress when avoiding installing additional the laggard windrow weldering of frock; The 3rd step was placed in frock on the junk mill body 9, with holding screw 1 frock was fixed on the junk mill body 9, and regulated holding screw 1 and make the built-up welding contact layer 7 of frock inboard identical with junk mill body 9 top outer gaps, and the thin and thick of assurance overlay cladding is even; In the 4th step, on the junk mill body, carry out built-up welding with YD type hard alloy composite material surfacing welding; The 5th step, after finishing, welding unclamps interior card, take off welding tooling.Finish welding.
Also be provided with and the identical wild card of interior card quantity in the frock body outside, screw rod passes wild card and is connected on the interior card, and the nut on the screw rod contacts with the wild card outer surface.
